EARL THOMPSON, OF NEW YORK, N. Y.

DESK-CHAIR.

To all wk om it may concern Be it known that l, EARL THOMPSON, a citizenof the United States, residing; at the city of New York, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Desk-Chairs, of which. the followinp' is aspecification.

My invention relates to improvements in desk chairs and the object of myinvention is to provide a simple and convenient device for the saidpurpose. Another object of my invention is to provide a desk chair unitwhich is adjustable to correct the tendency of the occupant to assume anincorrect posture. Permanentdeformity is found to result from incorrectposture assumed in childhood and during the formative period of schoollife by reason of the inelasticity of the school seat and desk. It isdesirable to combine in a desk chair unit means for adjusting theposition of the desk from and toward the seat which is known the plusand minus adjustment, means for adjusting: the height of the seat sothat the feet of the pupil will rest comfortably and depressing the deskin its relation to the seat to attain the proper height for use, andalso to provide means for adjustably inclining the desk table to preventeye strain and a further object of my invention is to provide a deskchair unit by which the above mentioned desired results are severallyand collectively attained.

1 accomplish this object by the device illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of my improved deskchair.

Fig. 2 is a section of the same on the line 2-2 in Fig. 1, and

Fig. 3 is a section of the adjustable leg.

Similar characters refer to similar parts throughout the several views.

My improved desk chair unit comprises chair 1, and pedestal 2 upon whichpedestal may be provided a book rack 3, or the like. On the pedestal 2 Imount two or more brackets 45 which are vertically adjustable on thepedestal and for which purpose 1 prefor to use the slot and binding studshown in my Patent 1,199,510.

The bracket 4 supports a desk member which u'eferably comprises a bedsection 5 having a desk tablet 6 secured to its inner Specification ofLetters Patent. Paizgntgd App. 26, 1921,

marginal edge by a hinge 7 or the like whereby the desk tablet 6 may beinclined at any desired angle. The bed 5 may be constructed in anydesired manner or form or may be omitted and the desk tablet attacheddirectly to the bracket 4:, without departing from the spirit of myinvention. Any desired means may be employed for elevating orsupportingthe desk tablet 6 at the desired angle, but I prefer to usefor thispur-v pose the screw 9 as hereinafter described. The desk memberis adapted to be moved in and out to adjust its position horizontally tothe needs of the user. I preferably use for this purpose runners formedof sheet metal strips bolted upon the bed and bracket respectively andhaving their freeedge sections bent over to slidably engage each other.

1n the bed 5 lprovide a screw 9 which bears against and is preferablyembedded in a plate 10 on the underside of the tablet 6 and is operatedby a wheel 11, or the like. The.

outer edge section or strip 12 of the tablet 6 is hung on a hinge 13 sothat it will take a horizonal position, as shown in Fig. 1, as shelfwhen the tablet 6 is raised, the movement of the strip 12 being; limitedby a cutout section 12 of the strip 12, on the underside thereof. On thebed 5 are'provided a plurality of knobs 141, 14 to serve as rests forthe tablet 6 when in its depressed position.

I adjust my improved chair in'height to the needs of the user by meansof screw threaded extension sections 15, 15 inserted in the legs 16, 16of the chair 1 and provide a lock 1'7 on each of the screws 15, forlocking the same in the desired position. The screws 15 are eachpreferably provided with balls or casters 18.

Elly device being; thus assembled may be adjusted to the height andrequirements of the user by extending the screws 15 of the legs 16 andturning down the lock nuts 17. As the adjustable bed is preferably sup-'ported at one side only of the chair 1 it does not interfere with aperson seating himself at the desk, and the desk may be readily movedtoward or from the user by means of the slide or runners as abovedescribed. The tablet 6 may be adjusted to a horizontal position bywithdrawing the screw 9 or may be adjusted to an inclined position byturning the screw 9 upward as desired.

Having thus described my invention, what I claim is: v

1. In a device of the character described, the combination of apedestal, a bracket member on the pedestal a bed member supported on thebracket and adapted to be adjusted horizontally, a desk tablet hinged tothe bed member at their inner marginal edges, whereby the desk membermay be inclined, and a shelf section on the outer edge of the desktablet and supported solely thereby in a horizontal position when thetablet is inclined.

2. In a device of the character described, the combination of apedestal, a bed on the pedestal, a desk tablet hinged thereon at itsinner marginal edge, a screw adapted to adjust the angle of inclinationof the tablet, a shelf hinged upon the tablet at its outer edge andsupported solely by the tablet in a horizontal position when the tabletis inclined.

3. In a desk chair unit, the combination and from the chair including abracket on I the pedestal, a bed supported on the bracket, runnersproviding a sliding connection bctween the bracket and the bed, a hingeconnection between the bed and the tablet at their inner edges, a screwfor positioning the tablet in an inclined position to' the bed and ashelf supported solely by the tablet at its outer marginal edge andadapted to assume a horizontal position when the tab let is inclined.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, this 15th day of December 1917.
